Abstract
Description
Mit luftgekühlten Radbremsen ausgerüstetes Fahrzeug Vehicle equipped with air-cooled wheel brakes
Die Erfindung betrifft ein mit luftgekühlten Radbremsen ausgerüstetes Fahrzeug, insbesondere ein Kraftfahrzeug.The invention relates to an equipped with air-cooled wheel brakes Vehicle, in particular a motor vehicle.
Bekanntlich wandeln die den Rädern von Kraftfahrzeugen zugeordneten Bremsen kinetische Energie des Fahrzeugs durch Reibung in Wärme um, die auf geeignete Weise abgeführt werden muß. Dies geschieht in der Praxis durch Flüssigkeitskühlung der Bremsen, was relativ komplizierte Konstruktionen erfordert, oder durch Luftkühlung, wozu es bekannt ist, beispielweise in Radzierblenden Luftleitvorrichtungen oder in Stoßstangen bzw. Spoilern Öffnungen zum Eintritt von Luft unter der Wirkung des Fahrtwinds vorzusehen.As is known, convert the assigned to the wheels of motor vehicles Braking kinetic energy of the vehicle through friction into heat, which is suitable Way must be discharged. In practice, this is done using liquid cooling the brakes, which requires relatively complex constructions, or by air cooling, what it is known for, for example in wheel covers or air guiding devices in bumpers or spoilers openings for the entry of air under the effect of the Provide airflow.
Der Erfindung liegt die Aufgabe zugrunde, eine Luftkühlung für die den Rädern zugeordneten Bremsen zu schaffen, die ohne Beeinträchtigung des Fahrzeugaufbaus mit einfachen Mitteln realisiert werden kann und sich auch nachträglich am Fahrzeug anbringen läßt.The invention has for its object to provide air cooling for to create brakes associated with the wheels without impairing the vehicle structure can be implemented with simple means and can also be retrofitted to the vehicle can be attached.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Patentanspruchs 1, vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the characterizing Features of claim 1, describe advantageous embodiments of the invention the subclaims.
Die erfindungsgemäße Lösung des skizzierten Problems ist insofern besonders günstig, als das zumindesteineLuftleitprofil zugleich die Aufgabe eines üblichen Frontspoilers übernehmen bzw. bei Vorhanden spin eines separaten Frontspoilers diesen unterstützen kann. Ein Frontspoiler dient bekanntlich dazu, bei hohen Geschwindigkeiten die Bodenhaftung des Fahrzeugs zu gewährleisten bzw. zu erhöhen.The inventive solution to the problem outlined is insofar particularly favorable, as the at least one air guiding profile also serves as the function of one take over the usual front spoiler or, if available, spin a separate front spoiler can support this. A front spoiler is known to be used at high speeds to ensure or increase the road grip of the vehicle.
Zwei Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichnung erläutert. Es zeigen: Die Fig. 1 u. 2 in einem Längsschnitt durch das Fahrzeug bzw. in Draufsicht ein erstes Ausführungsbeispiel und die Fig. 3 u. 4 in einem Längsschnitt bzw. in Draufsicht ein zweites Ausführungsbeispiel der Erfindung.Two embodiments of the invention are based on the following the drawing explained. 1 and 2 in a longitudinal section through the vehicle or in plan view a first embodiment and Figs. 3 u. 4 shows a second exemplary embodiment of the invention in a longitudinal section or in plan view.
Betrachtet man zunächst die Fig. 1 und 2, so erkennt man von dem eigentlichen Fahrzeug im wesentlichen nur den Vorderwagen 1 sowie die beiden Vorderräder 2 und 3. Die Vorderräder sind mit im einzelnen nicht dargestellten, da einen bekannten Aufbau besitzenden Scheiben- oder Trommelbremsen ausgerüstet, die in üblicher Weise zum Abbremsen des Fahrzeugs durch Umwandeln von kinetischer Energie in Wärme dienen.If one looks first at FIGS. 1 and 2, one recognizes the actual one Vehicle essentially only the front vehicle 1 and the two front wheels 2 and 3. The front wheels are not shown in detail because they are known Structure owning disc or drum brakes equipped in the usual way serve to brake the vehicle by converting kinetic energy into heat.
Zur Kühlung der Bremsen sind über den glatt gehaltenen Unterboden 4 des Fahrzeugs nach unten überstehende Luftleitprofile vorgesehen. In dem in Fig. 1 und 2 dargestellten Ausführungsbeispiele der Erfindung ist ein den Bremsen der beiden Vorderräder 2 und 3 gemeinsames rnittleres Luftleitprofil 5 vorgesehen, das einen Bestandteil des ferner die Seitenteile 6 und 7 enthaltenden Frontspoilers 8 bildet und einen Teil des Fahrtwinds auf in Fahrtrichtung hinter ihm angeordneten individuelle Luftleitvorrichtungen 9 und 10 lenkt, von denen jede einer der Bremsen zugeordnet ist. Wie insbesondere Fig. 1 erkennen läßt, können die individuellen Luftleitvorrichtungen 9 und 10 etwas weiter nach unten vorstehen, damit sie nicht im Windschatten der Seitenteile 6 und 7 des Frontspoilers 8 liegen.To cool the brakes are on the smooth underbody 4 of the vehicle provided air guide profiles protruding downwards. In the one shown in Fig. 1 and 2 illustrated embodiments of the invention is the brakes of the two front wheels 2 and 3 common rnittleres air guide profile 5 provided, the a component of the front spoiler also containing the side parts 6 and 7 8 forms and a part of the airstream is arranged behind him in the direction of travel individual vanes 9 and 10, each of which directs one of the brakes assigned. As can be seen in particular from FIG. 1, the individual Air guiding devices 9 and 10 protrude a little further down so that they do not lie in the slipstream of the side parts 6 and 7 of the front spoiler 8.
Auch in dem Ausführungsbeispiel nach den Fig. 3 und 4 sind wieder die Verhältnisse im Bereich der Vorderräder 20 und 21, d.h. im Bereich des Vorderwagens 22 des Kraftfahrzeugs, betrachtet. In diesem fiu;f;jhrungsbeispiel besitzt das Fahrzeug einen separaten, sich über die gesamte Fahrzeugbreite erstreckenden Frontspoiler 23, dem zur Kühlung der Bremsen der Vorderräder 20 und 21 ein den Bremsen der Vorderräder gemeinsames Luftleitprofil 24 nachgeschaltet ist. Dieses Luftleitprofil erstreckt sich bis möglichst nahe vor die Bremsen, wobei der Schwenkwinkel der lenkbaren Räder 20 und 21 berücksichtigt werden muß.Also in the embodiment according to FIGS. 3 and 4 are again the conditions in the area of the front wheels 20 and 21, i.e. in the area of the front end of the vehicle 22 of the motor vehicle. In this example, the vehicle owns a separate front spoiler that extends over the entire width of the vehicle 23, the one for cooling the brakes of the front wheels 20 and 21 and the brakes of the front wheels common air guide profile 24 is connected downstream. This air guide extends as close as possible to the brakes, with the swivel angle of the steerable wheels 20 and 21 must be taken into account.
Wie Fig. 3 zeigt, ragt das Luftleitprofil 24 nach unten über den Spoiler 23 hinaus, so daß seine "Fangwirkung" für den Fahrtwind durch den Spoiler 23 nicht beeinträchtigt wird.As FIG. 3 shows, the air guiding profile 24 protrudes downward over the spoiler 23 so that its "catching effect" for the airflow through the spoiler 23 is not is affected.
Aus Fig. 3 ist ferner deutlich erkennbar, daß in Längsschnitten durch das Fahrzeug das Luftleitprofil 24 (übrigens wie auch die individuellen Luftleitprofile 9 und 10 in den Fig. 1 und 2) eine solche Querschnittsform besitzt, daß seine Unterkante 24' in Fahrtrichtung des Fahrzeugs vorsteht, die Luftleitvorrichtung also schaufelförmig den Fahrtwind zu den Bremsen lenkt.From Fig. 3 it can also be clearly seen that in longitudinal sections through the vehicle has the air guide profile 24 (by the way, as well as the individual air guide profiles 9 and 10 in Figs. 1 and 2) has such a cross-sectional shape that its lower edge 24 'protrudes in the direction of travel of the vehicle, so the air guiding device is shovel-shaped directs the wind to the brakes.
Bei einer figürlich nicht dargestellten weiteren Ausführungsform der Erfindung sind nur die in den Fig. 1 und 2 mit 9 und 10 bezeichneten individuellen Luftleitprofile vorhanden, die dann beispielsweise an den Achslenkern der Räder 2 und 3 befestigt sein können.In a further embodiment not shown figuratively Invention are only those designated in FIGS. 1 and 2 with 9 and 10 individual Air guide profiles are available, which then, for example, on the axle links of the wheels 2 and 3 can be attached.
Wie aus der Beschreibung ersichtlich, gestattet die Erfindung in einfacher Weise eine Anpassung an die jeweiligen Erfordernisse auch stilistischer Art.As can be seen from the description, the invention allows in simpler An adaptation to the respective requirements, also of a stylistic nature.
